In terms of microbial pathogenicity, molecular Koch's postulates are a set of experimental criteria that show:
A microbe is the aetiological agent of a disease
A gene encodes a product that contributes to disease
A gene encodes a product that contributes to immunity to a disease
A mutation does not contribute to disease
